    专利说明:

    The invention relates to a cart for transporting goods by a single human force, the cart having a tub, a handle and two wheels on the long sides of the cart. The invention also relates to a towing device with a connection for detachable attachment to a trailer hitch of a motor vehicle and with an adapter for detachable attachment of a cart.
    In previously known towing devices for carts at the rear of a motor vehicle, a coupling part is screwed to the cart or is permanently connected in some other way, a counterpart coupling part remains firmly connected to the ball head of the trailer coupling. This has the disadvantage that the weight of the cart increases during assembly and disassembly by the coupling part.
    It is also difficult for a person who uses a cart with a firmly connected coupling part to fix the cart to the ball head in the loaded state, since at the same time the cart is held in position and the coupling with the carrier part either via a tensioning lever or through a clamping screw on the ball head must be fixed. In addition, the coupling part is only intended for one version of a cart. In carts that are designed as add-on carts, the coupling part, which weighs several kilograms, must always be transported with all other uses, which results in additional weight and a one-sided load on the cart.
    The object of the invention is therefore to provide a combination of a cart and hitch for connecting a cart to the motor vehicle, which overcomes the disadvantages of the prior art and which is easy to assemble, easy to use, and keeps the total weight of the parts used as low as possible , less prone to failure and easy to use, ie easy when attaching and detaching the cart from the hitch. The cart according to the invention achieves this in that a projection for locking into a locking device is provided on a long side of the cart, and at least one wheel can be removed from an axle, and the free end of the axle when the wheel is not attached to the axle , is designed as a pin for insertion into a receptacle.
    / 27
    A preferred embodiment of the cart is characterized in that it has a seat for people, which can be placed on the tub and detachably attached.
    In one embodiment of the invention, a crane boom can be plugged onto the tub, the area of action of which is above the tub when the cart is parked.
    To further develop the invention, the handle can be removed from the cart.
    In one embodiment of the invention, the handle is a hammer when it is removed from the cart.
    The hitching device according to the invention achieves the tasks set in that the adapter has a receiving piece for inserting a pin of a cart and a latching hook for holding and locking a projection of a cart.
    A preferred embodiment of the towing device is characterized in that the latching hook is a lockable lever or a square tube with a locking pin.
    In one embodiment of the invention there is a set for the recovery and processing of piece goods by individual persons, / 27 comprising a cart according to the invention and a trailer device according to the invention.
    In one embodiment of the set, the set further comprises a crane boom, which can be plugged onto the tub of the trolley, the effective area of which is above the tub when the trolley is parked, and the crane boom can also be plugged onto the towing device.
    For a further embodiment of the invention, the set further comprises a stand which can be plugged onto the handle of the cart, the effective range of which is above the tub when the cart is parked, and the stand can also be plugged onto the hitch.
    The invention is explained below with reference to an embodiment shown in the drawings. 1 shows an oblique view of the cart, FIGS. 2 and 3 show an oblique view of the towing device mounted on a motor vehicle, FIG. 4 shows a section of an oblique view of the cart as it is attached to the towing device, FIG. 5 shows an oblique view the cart with crane boom, FIG. 6 an oblique view of the towing device with crane boom, FIGS. 7 and 8 an oblique view of the cart with stand, FIG. 9 a / 27
    Oblique view of the cart with the bench and table attached, and FIG. 10 shows the side view of the handle of the cart.
    1 to 4, the cart 1 and the hitch 7 form a classic pair of interrelated products, since the inventive concept goes back to easily and best possible to assemble and detach the cart 1 on the hitch 7. 1, a cart 1 is provided, with which almost any objects, such as bulk or piece goods, can be easily transported by a person, and the cart 1 has features, whereby it is used as a rear carrier for a vehicle, such as a motor vehicle can be and easily attached to the rear of a vehicle in the loaded or unloaded state and can also be detached from it. The cart 1 essentially has a trough 2 and on each of its two longitudinal sides a wheel 4 and finally a handle 3 in order to push, pull, steer, lift the cart 1 by hand, etc. Already shown in FIG. 1 that the handle 3 can be detachably fastened to the cart 1, in particular to the tub 2. In the embodiment shown, the handle 3 is inserted in the direction of arrow A into a square tube 15 and secured with a locking pin 16. The detachability of the handle 3 has various advantages. Firstly, the cart 1 can be made lighter or less bulky at the rear of a vehicle / 27 during transport. Second, other elements for other uses can be mounted on the square tube 15 as needed (see below).
    2 and 3, the hitch 7 is shown as it is already mounted on the ball head of a hitch 14 of a motor vehicle 13. In the prior art, the mechanical elements are known, by means of which the towing device 7 can be fastened sufficiently securely and in the desired straight alignment on the ball head of the trailer coupling 14 and can also be released again. The hitch 7 is connected on its side facing away from the motor vehicle to an adapter 5, to which a cart 1 can be connected at two points. This is on the one hand a receiving piece 8a, on which a projection can be pushed. The receptacle piece 8a is designed as a piece of pipe, so that a larger piece of pipe can be pushed onto the receptacle piece 8a, or a smaller piece of pipe with a smaller diameter can be inserted into the receptacle piece 8a. On the other hand, seen in the direction of gravity, there is a latching hook 8b in which a second mechanical element of the cart 1 can be inserted and fixed. The bracket at two points has special advantages. The loaded cart 1 can first be attached to the receptacle 8a and thereby receives a sufficiently defined position for final locking. The locking / 27 can be done with the locking hook 8b, without the cart 1 with a high
    Still need to balance weight. The adapter can also be configured differently than shown in the figures. Another
    re embodiment can e.g. be suitable for further and
    to accommodate different types of containers, and alternatively also a bicycle rack.
    According to the embodiment Fig. 2 is the locking hook 8b
    Lever 10 executed, on which a foldable bracket 9 is attached.
    According to the embodiment Fig. 3 is the locking hook 8b
    Section of a square tube 11 formed, in which
    also a square tube piece of a smaller width
    bar, and the locking is done by a locking pin.
    4 is the connection the cart 1 with the trailer
    direction 7 shown according to the embodiment of FIG. 2. For the purpose of attaching the cart 1 to the hitch 7, the wheel 4 is removed from the axle 6. The free end of the axis then serves as a mechanical element which can be inserted into the receptacle 8a. The cart 1 also has a projection 17 at a suitable point and of a suitable extent, which can be grasped by the bracket 9. If the lever 10 is then turned in a known manner, the cart 1 is firmly attached to the hitch 7 and, via the coupling 14, is also firmly attached to the rear of the motor vehicle 13. The cart 1 is easy to assemble in this way and also simple Way to separate from the motor vehicle again. The particular advantage of this solution is that the connection and disconnection of the cart 1 from the motor vehicle 13 can be carried out by a single person even when loaded. The locking by lever 10 and the securing by means of corresponding rings or pins, such as, for example, a locking pin 12 according to the embodiment from FIG. 3, can be achieved with one hand.
    The cart 1 according to the invention and the towing device 7 unfold their advantages particularly in applications in the hunting area. Hunters have to process, wash and transport killed game. They are regularly on their own and can use tools with multiple functions.
    5, the cart 1 is designed such that it can be connected to a crane boom 19. For this purpose, the handle 3 of the cart 1 has a plug connection with the crane boom 19, which essentially represents an extension of the handle 3 and projects over the loading area of the tub 2 when the cart 1 is parked in one of several ways. 5/27 it can also be seen that there is a kink or an angle between the handle 3 and the crane boom 19 in order to make this better possible. The crane boom 19 is equipped with a cable winch 20, as a result of which game lying near the cart 1 can be pulled up, seen in the direction of gravity raised above the tub 2, processed in this state and can also be lowered vertically into the tub 2. The trough 2 is therefore located vertically below the highest point of the winch 20 on the crane boom
    19th
    In order to provide further functions, the crane boom 19 is alternatively connected to the towing device 7 via an extension piece 18. For this purpose, the hitch 7 has a plug-in option at least for the extension piece 18. The extension piece 18 is required to enable a practical height of the crane boom 19, because the height of the hitch 7 is regularly in the range of only 20 to 60 cm above the ground. In the manner shown in Fig. 6, however, a crane boom 19 is obtained, also with a cable winch 20, for pulling, lifting and washing piece goods, e.g., as already mentioned, of game that has been shot. For the special washing process, a tank 21 (e.g. for rinsing water) with a hose 22 is also provided on the crane boom 19. In this way, a washing facility is advantageously obtained without an electric or other driven / 27
    Water pump would be required. The fact that the piece goods to be washed hangs in the air during the washing process also ensures hygiene. In addition, it is advantageous that the hanging general cargo is already in the vicinity of either the trunk of the motor vehicle 13 or in the vicinity of the cart 1, which is to be attached to the hitch 7 anyway.
    A stand 24 can also be fastened to the handle 3 of the cart 1 in a manner similar to the crane boom 19, as shown in FIG. 7. The connection between the stand 24 and the handle 3 takes place via a receiving piece 25. The stand 24 can have brackets 26 with holes 27, into which piece goods can be hung above the tub 2 using hooks (not shown). Analogous to the crane boom 19, the dimensions and angles of the cart 1, handle 3 and stand 24 to one another are dimensioned such that the holes 27 in the state where the cart 1 is securely and firmly parked in a desired manner, seen in the direction of gravity over the surface of the Trough 2 lie, so that the mode of operation of the stand 24 in this embodiment lies over the area of action of the cart 1.
    This part of the invention can be seen in an exploded view in FIG. 8 and clarifies how a few parts can be plugged into one another in a simple and immediately learnable manner in order to / 27. .....
    use this tool for hunting, for example. The receiving piece 25 uses the same plug mechanism on the handle 3 as the crane boom 19th
    Due to the existing mechanical features of the cart 1, its function can also be easily expanded again with a few further devices. In Fig. 9 the cart 1 is parked stable and connected to a bench 28 and a table 29. In this way, the cart 1 can again be used for the hunter as a resting place or as a spy point; Likewise, the cart 1 can also be used in other contexts as a rest area or play area. First, the cart 1 is simply parked. The bench surface of the bench 28 is then placed on the upper edge of the tub 2 and, if necessary, inserted into a suitable adapter. The bench 28 can also have a backrest. A person taking a seat on the bench 28 then sits on the bench 28 himself and stands with his feet outside the tub 2 of the cart 1. The table 29 can easily be attached to the receiving piece 25 which has already been used for the stand 23 if it has a suitable mechanical element. The table 29 can be pivoted about the receiving piece 25 in the direction of the arrow B in order to facilitate getting up and sitting down on the bench 28. Through the further use of the receiving piece 25, the functions of the cart 1 are increased / 27 ** 12 · -....... ’without unnecessarily increasing the number of equipment required. The table of the stand 23 shown in FIGS. 7 and 8 can also be used as the table 29. Due to the extension piece 24, this table is arranged significantly higher with respect to the seat of the bench 28, so that this table cannot be used for writing, resting or for a snack, but for supporting the hunter or arms during the hunt while the hunter is on the bench 28 sits.
    The handle 3, which is required anyway for the cart 1 and is designed to be removable for the various functions already described above, such as the space-saving transport of the empty cart 1 in a trunk, can be expanded by further functions. According to FIG. 10, the handle 3 can also be used as a hammer, the two ends 30, 31 of the handle 3 being shaped differently in order to also perform two different functions. At one end 30 of the handle 3 there is a flattened portion, so that the handle 3 moved in the direction C acts as a hammer, and the other end 31 is designed as a pimple to move in the direction D just to act as such a pimple.
    Some or all parts of the connection described above can be combined into a set which, when disassembled, has little weight / 27 and little volume in view of the numerous functions. For example, the set can be operated, assembled and disassembled quickly and easily by a single person and can be stored in the trunk of a motor vehicle. The set contains at least the cart 1 according to the invention and the trailer device 7, but can be expanded as desired by the crane boom 19 and / or the stand 23, 24 and / or the handle 3 and / or the bench 28 and the table 29.
